With this hybrid motor you will be able to use almost 35% less gas on your car. It will not use electricity, instead it will use the fumes the motor produces from the gas. When the gas is burnt the exhaust will go through a pipe and into a propeller chamber located on the axle of each wheel. When the fumes build up strong enough it will start turning the wheel and less gas will have to be used to make the wheel move. It will work kind of like a steam engine only that instead of steam it will use exhaust and instead of turning a propeller it will turn the wheels of the car.
